Micro Laser Systems further expand range with Fixed Wavelength and Fused Silica collimators

The Micro Laser Systems‘ FC Series of standard collimators are designed specifically for single mode fibre, polarisation maintaining fibre, and fibre laser applications requiring a pure Gaussian beam. The company has further expanded its range by offering several new designs.

All collimators

Fixed Wavelength
The FCX20 series is based on the standard FC20 Fibre Collimator but fixed at one wavelength. They offer a highly collimated, Gaussian beam with low wavefront error and are readily available in several popular wavelengths. The FCX20 comes with a 3 mm cable terminated with an FC or FC/APC connector.

Fused Silica
The FC5S and FC10S Fused Silica versions are of a multi-element design that delivers a highly collimated, Gaussian beam with low wavefront error. The lockable adjustable focus feature enables focusing a very tight spot at a great distance, or expansion of the beam to illuminate an area.

Micro Laser Systems is also able to manufacture custom collimators, being responsible for the whole project from design, through manufacturing, to final assembly and test. Please contact us to discuss your requirements.

New SWIR laser collimators from Micro Laser Systems

With the introduction of a 2 µm optical coating, Micro Laser Systems (µLS) have significantly broadened the available wavelengths their standard FC laser collimators can operate in. µLS can now offer collimators in four wavebands that cover the 350 to 2300 nm spectral range.

Designed specifically for single mode fibre, polarisation maintaining fibre, and fibre laser applications requiring a pure Gaussian beam, the µLS FC collimators deliver a very clean output with no diffraction patterns or beam distortions from apertures up to 45 mm in diameter.

Micro Laser Systems’ FC Series collimators can be used with any commercially available fibre-coupled laser, including Ar, YAG, TiS, HeNe, or DPSS systems.

For more information, visit our Micro Laser Systems (µLS) pages, or contact us.


Micro Laser Systems adds new fibre products to its range

Micro Laser Systems manufacture diode laser modules and optical assemblies with an emphasis on providing diffraction limited, circular beams with low wavefront error and low divergence. The California-based company has recently developed a new range of products which we are pleased to introduce to the UK and Ireland.

Fibre Focuser

Fiber Focuser-14_43The Micro Laser Systems’ Fibre Focuser generates diffraction limited micron spot sizes at long working distance via its multi-element air spaced Focusing Cell. This element screws onto the main collimator to provide a convenient and compact way to define the focused spot. This method avoids additional optic holders and alignment problems. The Fibre Focuser can be adjusted to work optimally with singlemode fibres, polarisation maintaining (PM) fibres and large mode area (LMA) fibres at any one wavelength within the limits of its AR coating.

The Fibre Focuser’s optical materials have been chosen to eliminate or minimise laser-induced fluorescence, especially in the visible, and are housed in a stainless steel body to shield from the effects of temperature. Custom options, such as alternative housing materials for hazardous environments, mounting holes or slots, and special wavelength ranges, can be ordered.

Fibre Receiver

FiberReceiver_43The FR10 Fibre Receiver has been designed to collect reasonably collimated light and inject it into a 100 µm or larger core fibre with greater than 90% efficiency. The FR10 has been specially engineered specifically by Micro Laser Systems for this task, delivering a much larger signal than if using a reversed collimator in the same situation.

Housed in stainless steel and fitted with an SMA connector, the FR10 Fibre Receiver is delivered with a factory preset focus for collimated light. However, if you are working at the lower or upper end of the spectrum, or if the light source is not as collimated as one would like, focus can be user adjusted for better coupling and optimal signal strength.

The receiver’s 10 mm aperture is threaded to accept sensors or ½” inch optics such as filters. Extra items can be added via the convenience of the FL10 Cell mount, and a ring adapter for mounting to common optical mounts and optical fibre assemblies is also available.

For more about these two products, visit our Micro Laser Systems pages on our website, or contact us directly for more information.

 

 


Micro Laser Systems expand range with UV, RGB and custom collimators

The Micro Laser Systems‘ FC Series of standard collimators are designed specifically for single mode fibre, polarisation maintaining fibre, and fibre laser applications requiring a pure Gaussian beam. The company has now added to this range by offering three new designs and a customisation service.

All collimatorsOptimised for UV applications in glass or fused silica, the FC5-UV has been specially coated for the 350 to 410 nm wavelength range. The lens system is also well corrected to give excellent beam quality and minimise fluorescence. An apochromatic collimator has also been developed for simultaneous transmission of RGB wavelengths without any distortion. Applications include projection systems, flow cytometry and microscopy.

Completing the line-up is the Fibre Focuser. Based on the FC10, it can accommodate various focusing optics and can therefore be optimised for single mode fibre, polarisation maintaining (PM) fibre, or large mode area (LMA) fibre. The multi-element design provides a tightly focused spot with good working distances. Custom Fibre Focusers can be produced for any focal length, spot size, or particular wavelength. They can also include other optical elements such as filters, polarisers, or windows. 

Micro Laser Systems is well positioned to manufacture custom collimators as they are responsible for the whole project: from design, through manufacturing, to final assembly and test. Please contact us to discuss your requirements.


New Green Diode Laser for the more demanding application

“Micro Laser Systems has designed this laser to ensure source imperfection is a thing of the past”

Micro Laser Systems (µLS) has introduced a high stability green diode laser with diffraction limited performance for more demanding applications. These include: confocal microscopy, flow cytometry, fluorescence excitation, particle analysis, direct laser writing and metrology.

This new laser in the Lepton IV OEM series delivers a circular Gaussian beam with high output stability, has a low power requirement, and is built into a smaller package size when compared to typical Argon and diode pumped lasers. Output power is up to 40 mW and can be continuous wave, pulsed, or modulated, while the low wavefront error allows for the generation of micron and  sub-micron spots sizes, or the production of a large clean beam for illumination.

The OEM units are available with or without temperature control – depending on your application – and are provided with numerous threaded mounting holes for secure installation.

For more information on this model, other wavelengths available in this series, or the extensive µLS range of collimators, free-space, and fibre-coupled lasers, then do contact us now.
